COMBINEDFR!CTION AND DIRECT-ACTING DRAFT-RIGGING.

SPECIFICATION forming part of Letters Patent No. 717,678, dated. January6, 1903. Application filed November 15, 1992. erial No. 131,459. (Nomodel.)

My invention relates to friction spring draftrigging.

The object of my invention is to provide'a combined friction anddirect-acting spring draft-rigging of a simple, compact, strong,efficient, and durable construction which may be cheaply manufacturedand readily and conveniently applied to the car.

My invention consists in the means I employ to accomplish thisresult-that is to say, it consists, in connection with a draw-bar anddraft-iron in line therewith having a straight friction-face-on one sideand double-incline friction-faces on its opposite side, atransversely-movable friction block having donble-incline friction-facesen gaging the doubleincline friction-faces on the draft-iron, and atransversely-arranged spring acting against said friction-block, of alongitudinally-arranged or direct-acting spring and followers thereforon the opposite side of the draft-iron from said transversely movablefrictionblock, so that the draft-iron is located centrally and directlybetween the direct-acting spring and the transversely-acting spring andits friction-block, the draft-iron having wings for operating thefollowers of the direct-acting spring.

It also consists, in connection with these parts, of a pair of sideplates or stop-castings secured to andbetween the draft-timbers orcenter sills of the car and provided with suitable transverse guides forthe transverselymovable friction block and a longitudinal case or guidefor the followers of the longitudinal or direct-acting spring.

It also consists in providing said side plates or stop castings withlaterallyremovable transverse bolts for securing the same together andwhich also serve as removable stops for the followers of thelongitudinallyacting spring, so that said spring and thefollowerstherefor may be inserted and removed through the open end of the guidewhen such removable stop-bolts are taken out and so that thedraft-timbers or center sills will not interfere with the removal ofsaid bolts.

It also consists in the novel construction of parts and devices and inthe novel combinations of parts and devices herein shown or described.

In the accompanying drawings, forming a part of this specification,Figure 1 is a vertical longitudinal section of a combined friction anddirect-acting spring draft-rigging embodying my invention, thesection-line being indicated by the line 1 1 on Fig. 2. Fig. 2 is a planview showing some of the parts partly broken away and others inhorizontal section. Fig. 3 is a cross-section on line 3 3 of Fig. 1.Fig. 4 is a detail sectional view showing the followers and thimbles forthe direct-actingspring. Fig. 5 is, a detail view of one of thethimbles. Fig. 6 is a detail perspective view of the draft-iron. Fig. 7is a detail perspective view of the side plates or stop-castings.

In said drawings, A represents the drafttimbers; A, the center sills; Athe crosssills; A the buffer-block, and A the carryiron.

B is the draw-bar of the coupler B.

D is the sliding friction-draw-bar extension or draft-iron, the samebeing directly in line with the draw-bar and connected theretoby a clipor yoke 12, passing through an eye at in the draw-bar extension ordraft-iron,the crosspivot d of which eye is slightly rounded or beveled,so that the draw-bar and coupler may have the necessary slight lateralvibratory movement as well as a vibratory movement up and down.

F F are the side plates or stop-castings, fitting being thedraft-timbers and securely attached thereto by bolts f.

The draft-iron D has a straight friction-face d on one side, preferablyits upper side, which is in sliding frictional engagement with thestationary friction plate or face G, said plate or face G being securelyfixed or anchored on the side plates or stop-castings F F, butpreferably made in a separate piece therefrom or not integral therewith.The draft-iron D has on its opposite side from the straightfriction-face d and preferably on its lower side double-inclinedfriction-faces d d, which cooperate with the double-inclinefrictionfaces h h of the transversely-movable friction-block H, which isacted upon by the transversely-arranged spring K. Thetransversely-movable friction-block H has a barrel or flange h toreceive the spring K, and the spring K is supported at its lower end bya removable spring seat or cup K, which is removably secured to the sideplates or stopcastings F by cotter bolts or pins K having keys K thepins or bolts K extending through suitable lugs f on the side plates orstop-castings. The side plates or stop-casting havetransversely-extending guides f for the friction-block H to reciprocatein or on transversely while holding the same in position longitudinallyin respect to the drawbarordraft-iron. Thesideplatesorstop-castings areprovided directly opposite or above the friction-block and itstransverse guides f with alongitudinal guide f to receive thelongitudinally-arranged direct-acting spring N and its followers P P,the followers P P being preferably circular and the longitudinal guide ftherefor preferably cylindrical in form. The guide f is preferablyformed one-half upon each of the side plates or stopcastings F and hasopen ends to facilitate the insertion and removal of the spring N andfollowers P. The stops ]"f for the followers P Pto abut against arepreferably made in separate pieces and removable from the guide f andthe side plates or stop-castings upon which said guide is formed. Theseremovable stops f f may preferably also serve as bolts for bolting orsecuring together the two side plates or stop-castings F F. These boltsare preferably laterally removable from the guides f of the side platesor stop-castings, this being conveniently effected by providing theholes f through which the bolts extend, with lateralopeningsf throughwhich the bolts may be removed laterally when their nuts are loosened.This prevents the draft-timbers or center sills from interfering withthe removal of the bolts, as they would do if the bolts had to bewithdrawn lengthwise instead of removed laterally.

The draft-iron D is provided with central upright wings d d foroperating the followers of the longitudinal or direct-acting spring.Thimbles P, having sockets p to receive the ends of the rod or stem 19',which extends through the spring N, are preferably inserted between thewings d and the followers P. A small spring N may, if desired, beinclosed within the main spring N. To cause the direct-acting spring Nto come first into action under either pulling or buffing strains andthe transversely-acting spring and frictionblock to come subsequentlyinto action, the incline friction-faces (1 cl on the draft-iron are morewidely separated than the cooperating friction-faces h h on thefriction-block, thus leaving some play for partial compresslonofthelongitudinal or direct-acting spring before the friction-blockbegins to compress the transverse spring K, and as the downward ortransverse movement of the friction-block H is somewhat less than thatof the followers P, I prefer to so arrange the parts that thedirect-acting spring N is slightly or partially compressed when appliedor assembled, as this enables me to use springs of the same size orlength and still have both fully compressed by the full movement of thedraftiron, and the strength of both is thus fully utilized.

' The draft-iron D is provided with the central web 01 bridging theincline friction-faces d d to strengthen the'draft-iron, and which Webfits in a corresponding slot formed in the friction-block H.
